Abstract: A method of manufacturing a conductivity cell comprises providing two cell block halves, each cell block half having a trough with an electrode arranged in the trough, an inlet flow path leading to the trough, and an outlet flow path leading from the trough; covering the electrode with a curable adhesive and curing the adhesive; removing a portion of the cured adhesive to expose a portion of the electrode along the trough, wherein the exposed portion of the electrode is substantially continuous with the adjacent surfaces of the inlet flow path and the outlet flow path; and joining the two halves together with their respective troughs aligned to form a conductivity cell.

Abstract: Methods for determining the amount of volatile electrolyte present in an aqueous liquid sample comprise transferring the electrolyte from the aqueous liquid sample to an absorber solution across a gas-permeable membrane which is non-passable to the aqueous liquid sample and measuring the change in electrical conductivity of the absorber solution during the transfer period. The absorber solution contains a solute which enhances the transfer of the electrolyte. Apparatus for conducting such methods include an absorber solution containing a solute which enhances the transfer of the electrolyte.
